Isaac Newton's color sequence (red, orange, yellow, green, blue, indigo, violet) is kept alive today by several popular mnemonics. One is simply the nonsense word roygbiv, which is an acronym for the seven colors. [5] This word can also be envisioned as a person's name, "Roy G. Biv". [6]
ROYGBIV (in reverse VIBGYOR) is commonly used to remember the order of colors in the visible light spectrum, as seen in a rainbow. Richard of York gave battle in vain" (red, orange, yellow, green, blue, indigo, violet). Additionally, the fictitious name Roy G. Biv can be used as well. (red, orange, yellow, green, blue, indigo, violet).
White light is dispersed by a glass prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light).
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
VIBGYOR (Violet–Indigo–Blue–Green–Yellow–Orange–Red) is a popular mnemonic device used for memorizing the traditional optical spectrum. VIBGYOR may refer to: ROYGBIV , the exact reverse of VIBGYOR; the sequence of hues commonly ascribed to the rainbow colors
The spectrum above shows approximate wavelengths (in nm) for spectral colors in the visible range. Spectral colors have 100% purity, and are fully saturated. A complex mixture of spectral colors can be used to describe any color, which is the definition of a light power spectrum. The spectral colors form a continuous spectrum, and how it is ...

Colour distribution of a Newton disk. The Newton disk, also known as the disappearing color disk, is a well-known physics experiment with a rotating disk with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when it's spun rapidly about its axis.
